Answer:
-1/4x + 1 ( If this is wrong then ignore this)
Step-by-step explanation:
The formula for a problem like this is y - y1 = m(x - x1). The x coordinate, -8 is the x1 and the y coordinate 3 is x1. So the equation is y - 3 = -1/4(x + 8)
Equation:
y - 3 = -1/4(x + 8)
y - 3= -1/4x - 2
y = -1/4x + 1
Therefore the equation for the line is y = -1/4x + 1
Answer:
well does b= anything, if not I'm pretty sure just 8b
The probability that the student, who was chosen at random, was female and got an "A' on the test is <u>0.1645</u>.
<h3>What is probability?</h3>
Probability is the measurement of the likelihood of an event occurring.
The probability that an event occurs can be equal to or less than 1.
<h3>Data and Calculations:</h3>
Grades A B C Total
Male 18 4 17 39
Female 8 3 20 31
Total 26 7 37 70
Probability of being Female and getting an "A" = 0.1645 (31/70 x 26/70)
The probability of being female = 31/70
The probability of getting an "A" = 26/70
Thus, the probability is <u>0.1645</u>.

Answer:
![11\frac{170}{333}](https://tex.z-dn.net/?f=11%5Cfrac%7B170%7D%7B333%7D)
Step-by-step explanation:
let x=11.510510510...
multiply by 1000
1000x=11510.510510...
again multiply by 1000
1000,000 x=11510510.510510...
subtract
999,000 x=1,1 49 9,000
x=11,499,000/999000=3,833,000/333,000=3833/333

Rocco and Guilia can paint and finish together in 3 hours while Rocco alone can do it alone in 7 hours. Guilia at the rate of 1/r can finish the job expressed in the following equation. 1/3= 1/7+1/r. Getting r, r is equal to 5.25 hrs. Hence, Guilia can do painitng alone in 5.25 hrs.
